Separate compilation: Can't take address for reference type value defalloc.h(130)

[Vladislav]

Hello!

I want to split my program into several files.

I have created 3 files:

file1.h:

#ifndef _file1
#define _file1

#include <iostream>
#include <vector>

struct StructTest
{
	double x;
	double y;
	StructTest(double x, double y);
};
std::vector<StructTest> initialize();


#endif // _file1

file1.cpp:

#include "file1.h"
StructTest::StructTest(double x, double y) : x(x), y(y)
{
}

std::vector<StructTest> initialize()
{
	std::vector<StructTest> struct_test_vec_obj;
	for (int i = 0; i < 10; i++)
	{
		struct_test_vec_obj.push_back(StructTest(i, i * 10));
	}
	return struct_test_vec_obj;
}

Source.cpp:

#include <iostream>
#include "file1.h"

using namespace std;


int main()
{
	std::vector<StructTest> struct_test_vec_obj = initialize();
	for (int i = 0; i < struct_test_vec_obj.size(); i++)
	{
		cout << "x = " << struct_test_vec_obj[i].x << "; y = " << struct_test_vec_obj[i].y << endl;
	}

	//system("pause");
	return 0;
}

This code works in VS2013.

In order to compile this code in root I have added in rootlogon.c this code:

{
gROOT->ProcessLine(".L D:\\git_repositories\\Parser_signal_finder\\VS2013\\Parser\\Test\\file1.h");
gROOT->ProcessLine(".L D:\\git_repositories\\Parser_signal_finder\\VS2013\\Parser\\Test\\file1.cpp");
gROOT->ProcessLine(".L D:\\git_repositories\\Parser_signal_finder\\VS2013\\Parser\\Test\\Source.cpp");
}

I launch my code by the next command and have an error:

root -l
main()
Error: Can't take address for reference type value defalloc.h(130)

My version is

ROOT 5.34/36 (v5-34-36@v5-34-36, Apr 05 2016, 10:25:45 on win32)
CINT/ROOT C/C++ Interpreter version 5.18.00, July 2, 2010

Could you help?
Thank you in advance.

Best regards, Vladislav.
